Can someone clarify jumper settings on FUH724.

what will happen if you remove jumper?
have you looked at 4 wire thermostats at home depot? google 4 wire thermostat for more info.

• Red wire: Power (24V input in most cases).
• Green wire: Fan.
• White wire: Heating.
• Blue wire: Cooling.
• Rh: Heating power.
• Rc: Cooling power.

Just to clarify: With the door closed, the fuse will blow as soon as you plug the unit in? Have you checked all three microswitches? One acts as a crowbar.

Hi dtsorrell...

If your somewhat of a mechanic/electrician then you can by-pass the pressure switch by hooking the color coded motor wires together with the incoming color coded wires from your power cord in the proper order.
Plug it in and then check to see if it blows the breaker again, if it does then it is your motor that is faulty.
Please take time to rate me.

try fitting a new plug. if you do cut back the cord back at least 3 inches try it again. before you do check socket with another appliance.let me know if that fixed it or not

If you are only getting 120v to the dryer, you still have a breaker tripped. It should be right next to the single pole 30. It takes 2 breakers to get the 240v you need to run the dryer. Try resetting another breaker expecially the ones marked 30amp. You do need to get a double pole breaker installed even for safety reasons.

CHECK YOUR BREAKER IT MIGHT BE THAT YOU ARE 230V .. IF IT IS A WIDE BREAKER ITS 230 OR IF IT IS A SLIM BREAKER ITS 115V , A VOLT METER IS YOUR BEST FRIEND.. REMEMBER TO VOTE FOR YOUR FAVORITE FIXIT GUY ! THANKS JAY

Hi,
Either you blew the fuse on the air handler control board or you burnt out the air handler transformer.
The thing that blew the fuse is probably the contactor in the condenser unit. You will need to check out out cause of the outage before replacing the fuse or transformer.

I'd tell you ,but I have to bill you too...

More than likely what happen was the internal overload in the compressor was tripped and didnt reset for 5 hrs and when it did it popped the breaker. The compressor was probably already shot. Sorry

Jumpered the bimetal thermostat and everything worked smoothly. Tried to clean contacts in thermostat with no luck, so ordered a replacement. At least it was cheaper than the contactor.
